Over my years as a reporter and editor, I've seen my fair share of scare stories about a supposed link between autism and routine childhood vaccinations.
This dates back to a 1980s study published in the British medical journal, The Lancet. Other studies have not shown a correlation.
There's been plenty of evidence for years that the idea was bunk, but in the name of "balanced reporting," some pretty bad journalism was committed in allowing quackery to be passed off as legitimate medicine. (He said-she said journalism isn't just for politics).
